Description

FIELD OF TECHNOLOGY

The present invention relates to controlling a door without touching it with a door, the door leaf being provided with an opening mechanism, a closing mechanism and a control mechanism. The present invention also relates to a device for performing this method.

BACKGROUND OF THE INVENTION

Closing mechanisms that automatically close a door or gate are known in the art. These closing mechanisms usually consist of various springs or even hydraulic systems which, when opening doors or gates, accumulate a certain amount of energy expended when opening doors or gates, which is then used to automatically close these doors and gates. Said closing mechanisms are often provided with shock absorbing elements to prevent the door from slamming shut. These closing mechanisms are equipped, among other things, for example, doors in public spaces, for example, in public buildings, in order to automatically close areas, for example, public toilets and other similar objects.

In addition, from patent documents US 20090320236 A1 and JPH 0953365 A, devices are known which, when a door is opened normally by applying a hand force to the door leaf, accumulate a part of the energy that is expended when opening and which cannot be used during subsequent automatic closing, as well as energy which facilitates the opening of the door and which must be overcome by the force of the closing mechanism. A device is also known from JPH02167975A, which also provides for opening a door in a conventional manner, wherein when the door is half opened, then the door is fully opened and then completely closed by closing devices. In all the above devices, there is no control with the help of another part of the body, except by the hand, and activation is always necessary to move the sash.

Devices are also known, for example, from patent document US 20090145037, in which the mechanism for opening the door closing mechanism is provided in the direction of opening from a person with the help of a leg or other part of the body. From the patent document US 20130118085 A1 is also known a device located on the door frame having a lever mechanism with a spring that counteracts the force of the closing spring. The disadvantage is that when opening it is necessary to overcome the force of the closing mechanism. The described devices have a major drawback, consisting in the fact that the operator must simultaneously apply force and at the same time move away from the opening door. This complicates the use even for healthy people, and in practice, people with disabilities, older people or children cannot use such a device.

In addition, there are electrical devices for automatically opening and closing doors, a common drawback of which is the high cost, the need for a power source, regular reports of current, checks and electrical safety in difficult conditions.

A separate problem of public toilets is the transmission of infectious diseases through the hands of visitors, and its solution can only be the almost complete exclusion of contact between the hands and the door or its fittings, in particular when opening the door to yourself. The most serious this problem is in a situation in which a person leaving the toilet cubicle has no way to carry out hand hygiene and must touch dirty parts. A similar problem is typical for public spaces in general, which may include, for example, fast food places, restaurants and cafeterias, offices, cinemas, concert halls, schools and other similar places. To a small extent, this problem is also characteristic of sterile areas, for example, in operating rooms, hospitals, clean production facilities and other similar rooms. And finally, the above problem may even be in private areas.

The closest solution to the above problem in this regard is a door control device known from patent document CZ 304,182. In this decision, a device is disclosed in which the opening mechanism is controlled by the foot, and to open the door, it is necessary to exert force to overcome the closing mechanism built into the door. In the solution described in patent document GB 304,182, in accordance with this principle, considerable force is required to open the doors, and therefore, for example, for children or persons with disabilities, it becomes difficult to open the door.

Thus, the aim of the invention is to provide a method for controlling doors without touching a person’s hand and creating a device for a door control system that, when using the optimized control force, automatically opens and closes a door towards itself without touching a door leaf with a hand.

SUMMARY OF THE INVENTION

This problem has been solved, and the disadvantages of the known solutions of this type have been largely eliminated by using the door control method without touching a person’s hand in accordance with the invention, the principle of which is that the action of optimized external forces, while the door is closed, activates at the same time the opening and closing mechanism installed on the door leaf, and when opening the door, the closing mechanism is locked, and when the door is closed, the opening mechanism is blocked, and so In this way, the opening force and the closing force never counteract each other. The opening and closing mechanisms are activated by a drive mechanism, which is preferably located at the bottom of the door leaf. Obviously, if the control mechanism is only controlled by the foot, ideally with shoes on the sole, the control mechanism should be located at the bottom of the door leaf, preferably even at the lower edge of the door leaf.

The specified method of controlling a door without touching a person’s hand is performed using the proposed device, the principle of which is that the door leaf is equipped with an opening and closing mechanism, preferably mounted on the axis of the hinges, and these mechanisms are connected as a whole with the control mechanism on the bottom of the door leaf .

The control mechanism, which works according to the mechanical principle, is located at the bottom of the door leaf and allows you to open the door to yourself and from yourself with the help of the foot pedal, controlled by the foot.

Another possibility of controlling the doors is that the opening and closing mechanism is pneumatic.

The opening and closing mechanism may be, in a preferred embodiment, pneumohydraulic.

The opening and closing mechanism may be, in a preferred embodiment, a hydraulic energy storage device.

The opening and closing mechanism is equipped with a pivoting element, designed in such a way that when the drive mechanism is actuated, the pivoting element rotates either counterclockwise or, alternatively, in the direction of opening the door leaf 1.

The control mechanism located at the bottom of the door leaf is equipped with a pedal arm.

A significant advantage of the present invention is that the invention completely eliminates the need to touch the door leaf with your hand, as a result of which the risk of transmission of infectious diseases is significantly reduced, and visits to public toilet facilities are pleasant for visitors.

The described solution has a number of technical and economic advantages, including the ability to install on an existing door leaf, as well as the fact that this solution is not significantly affected by the function and operation of the door leaf. The proposed device can also be used to fix the door in the open position, and then you can again control the door without touching it with your hand. If the installed opening and closing mechanism is not used by the person who uses it, the unused closing and opening mechanism only works as a closing device. The entire system is designed to prevent any injury if used by a careless operator.

DETAILED DESCRIPTION OF THE INVENTION

Since the present invention relates to a control system for a single door leaf 1, made to operate independently of the control system of a possible second door leaf, for clarity, the invention is described in more detail below on the example of a single-leaf door.

The pivoting member 5 is substantially pivotable upon activation of the opening and closing mechanism, both in the direction of opening of the door leaf 1 and in the direction opposite to its opening. In one exemplary embodiment of the invention, the rotation of the pivoting element 5 occurs when activated against the direction of movement of the door leaf 1.

The control mechanism II can be implemented by various technical means. For the description, a variant with a stepped lever mechanism is used, which allows to optimize the control force with a smooth automatic change of the gear ratio in accordance with the invention PV2016-106.

In an exemplary embodiment, the opening element 14 and the closing element 17 are made in the form of torsion springs.

In FIG. 1, where a general view of the proposed door control device is shown, wall 2 is shown, for example, a partition between rooms, into which a frame 3 can be inserted, on which hinges 4, the first door leaf is suspended. This can be implemented, as shown, on single doors, as well as, not shown, on double doors.

The door leaf 1 is equipped with an opening and closing mechanism I, which can be equipped with a shock absorber on the market. In addition, the door leaf 1 is provided with a control mechanism II and a connecting element 23.

In this context, it should be noted that this can be either a right or a left door leaf 1 adjacent at least one of its edges in a closed position to the frame 3, as well as a so-called “rotating” door leaf 1, which can open in both sides of the wall 2 and which, using the opening and closing mechanism, and independently returns to the closed position, although with this conclusion it can be temporarily, even repeatedly with decreasing amplitude, accelerated on the other side of the wall 2.

The purpose of the invention, thus ensuring the possibility of opening the door 1 from itself and in particular to itself, as well as subsequent automatic closing without the need for a hand touch of the door, is achieved due to the fact that the door leaf 1 is additionally equipped with an opening and closing mechanism I, preferably in the lower parts of the door leaf 1, which can be activated by the control mechanism II and the connecting element 23, for example, by pressing the foot, as a result of which the door leaf 1 opens before by a walking person and then automatically closes. It is obvious that the opening and closing mechanism will be placed on that side of the door leaf 1, on which the door leaf 1 opens towards a passing person who otherwise would have to pull the door leaf 1 by himself. On the opposite side of the door leaf 1, on which the leaf is opened from a passing person, such a control mechanism II is not necessary, since a person passing in this direction can push the door leaf 1 with his foot, lower leg, shoulder, elbow, knee, orthopedic and the like. way. For uniform actuation on both sides of the door leaf 1, it is suitable that the control component A28 and the drive component B29 of the drive mechanism II are located on both sides of the leaf 1 for optimization, as shown in FIG. 2.

In the described embodiment, the door control system can be made in such a way that the opening and closing mechanism is pneumohydraulic, pneumatic or a hydraulic energy storage device.

For a number of reasons, the door control system may have a promising purely mechanical design in which the opening element 14 and the closing element 17 are made in the form of springs and are generally made in the form of an energy or energy storage device for opening and closing the door leaf 1.

In accordance with FIG. 3a, the opening and closing mechanism comprises a pivoting member 5, which is shown in FIG. 3d and preferably made in the form of a rotary segment also in the form of an energy or energy storage device, which, when the control mechanism II is activated by the driving forces 39 around this segment, temporarily pushes the opening element 14 and the closing element 17, as shown in FIG. 4a. The opening element 14 is shown in FIG. 3b and at one end, by means of the clamping element 15 of the opening element 14, is connected to the pivoting element 5, and at the other end, by means of the butt shoulder 16, abuts against the door frame 3 or directly against the wall. The second closing element 17 is fixed at one end through the shank 18 of the closing element 17 with the pivoting element 5, and rests against the gate 11 (which connects the upper hinge 10 and the lower hinge 12) with the other end, and therefore to the door leaf 1. The closing element 17 is installed with compression to hold the door wall 1 in the closed state. As shown in FIG. 4, when the rotary element 5 is rotated, energy is accumulated in the opening element 14, in which case the twisting of the opening spring simultaneously accumulates energy in the closing element 17 — in this case, the twisting of the closing spring. After rotation of the rotary element, the force of the opening element 14 does not counteract the force of the closing element 17. This can be realized in accordance with FIG. 4 s, on which the bolt 7 mounted on the rotary axis 8 and activated by the springs 9 of the bolt 7 (as shown in detail in Fig. 4d), while turning the rotary element 5, captures the fist 22, mounted on the collar 11 of the lower hinge 10 and the upper hinge 12 and, thus, on the door leaf 1 (as shown in Fig. 4A). Due to the fact that each end of the closing element 17 is connected to the door leaf 1, until the release of the constipation 7, the operation of the closing element 17 is blocked. The opening element 14 acts through the pivoting element 5, which brings the lock 7 to the fist 22 mounted on the collar 11 of the lower hinge 10a and the upper hinge 12, and, as a consequence, on the door leaf 1, which begins to open, as shown in FIG. 4s Since mechanical termination of the opening element 14 should also be guaranteed when the door 1 is completely or almost completely opened (so that the closing element 17 can slam the door 1 again), the lock 7 rests on the stopper 6, as shown in FIG. 5s The door leaf 1 together with the fist 22 leaves inertia at the point of contact with the bolt 7, when the door leaf abuts the bolt 7 in the stopper 6 mounted on the cover 20, attached by means of the fastening cover 21, on the frame 3 or wall 2, and returns to the disengaged position . On the door leaf 1, the unlocked locking element 17 starts to work, and the doors begin to close automatically. In this case, the fist 22 passes the lock 7 into the disengaged position shown in FIG. 5s

There is also the possibility that a passing person may hold the door leaf 1 until the constipation 7 is released, for example, as in the cases described above, with the foot. This, therefore, leads to the fact that the fist 22 of the door leaf 1 does not leave inertia at the point of contact with the lock 7 and therefore remains in the activated position, as shown in FIG. 5b. The door leaf 1 then remains in the open position until the operator, with a slight pressure, for example, also by the action of the foot on the door 1 in the direction of its opening, deactivates the lock 7 and thereby causes the closing element 17 to work. The same effect can be achieved and when the door is moved in the closing direction, when, after the release of the sash 1, this sash starts to open again, and as a result of inertia the lock 7 will be released according to the standard method described in the previous paragraph.

The control mechanism II in the mechanical embodiment can be located on one side of the door leaf 1. And while on the opposite side of the door leaf 1 on the same axis can be located the next pedal arm 34 (as shown in Fig. 2) without any additional devices. As a result of this, the opening and closing mechanism I and the entire door leaf 1 can be controlled in the same way on both sides, the opening and closing mechanism always being installed on the hinge side 4 of the door leaf 1 (as shown in Fig. 1).

Description of work

Deactivated state - FIG. 1, 2, 3a, 3b, 3c, 3d, 6a, 7a, 7b

In FIG. 2 and 6a, a drive mechanism II is shown, which has a pedal arm 34, to which a driving force 39 is applied, which is rotatable about the pivot axis 30 and which is also located on both sides of the first door leaf. At its other end, the pedal arm 34 is connected to the connecting element 23, which is guided through a pulley C32, rotatably mounted on the pin 33. The control component 28 and the control component B29 (if installed) are in the disengaged, upper position, and the rotary element 5 (in detail shown in Fig. 3e) is in the position shown in Fig. 3a.

In this case, the opening element 14 does not exert any force. The closing element 17 applies only a preload force, which keeps the door leaf 1 closed.

In this case, the opening element 14 does not exert any force. The closing element 17 develops only a preload force, which keeps the door leaf 1 in the closed state. The lock 7 is in an inactive position (as shown in Fig. 3c), because it rests on the stopper 6 on the housing 20, attached through a mounting cover 21 to the frame 3 and the wall 2, due to the tightened closing element 17, which overcomes the force of the spring 9 of the lock 7. The opening element 14 does not apply a pressing force or force, since the action of this element is blocked by both ends, which are opposed by the frame 3 or wall 2.

In FIG. 7a is a diagram illustrating operation when the opening and closing mechanism is activated by moving the pivot member 5 opposite to the opening direction of the first door leaf. In FIG. 7b is a diagram illustrating operation when the opening and closing mechanism is activated by moving the rotary member 5 in the direction of opening of the door leaf 1.

In FIG. 6a shows the control mechanism II in the deactivated state. In this case, the connecting element 23, guided through the pulley 32C, made for rotation on the pin 33, is anchored to the sliding base 27 of the connecting element 23. The sliding base 27 of the connecting element 23 is arranged to move along the adjustable arm 36 depending on the angle of rotation, which thus continuously changes the gear ratio, which in the deactivated state is minimal. The pedal arm 34 is mounted on the pivot pin 35, and the butt surface 37 is supported by the rotary bearing 31. This design prevents possible injury to a person who is on the side opposite to the operator while the pedal arms 34 are tilted.

Activated state, door opening - FIG. 4a, 4b, 4c, 4d, 6b

The control component A28 and the control component B29 (if installed) are activated, that is, moved to the lower position (as shown in Fig. 6b), and the rotary element 5 is rotated 90 degrees (as shown in Fig. 4a).

Due to the rotation of the pivoting member 5 through the torsion grip 15 of the opening member 14 and due to the second end abutting against the butt shoulder 16 of the opening member 14 of the frame 13 and the wall 2, the opening member 14 develops full power. The closure member 17 also develops full force when twisted through the gripper 18 of the closure member and by lowering the second end of the supporting arm 19 of the closure member 17 of the door leaf 1 (as shown in FIG. 4b). However, the action of the closing element is blocked, since the door leaf 1 counteracts both ends (as shown in Fig. 4c). In FIG. 4c also shows the mount 26 of the connecting member 23 on the pivoting member 5.

The lock 7 is in the activated position since it does not rest on the lock 6, and the spring 9 of the lock 7 holds the lock in the activated state (as shown in FIG. 4d). When moving the rotary element 5, which carries the lock 7 for the fist 22 mounted on the collar 11 of the lower hinge 10 and the upper hinge 12, the door leaf 1 passes the lock 7 for the fist 22 and is held thereon (as shown in Fig. 4c). After the person opening the door leaf 1 releases the control component 28 and the control component B29 and leaves the door leaf 1, the door leaf 1 begins to open under the action of the opening element 14.

In FIG. 6b shows a situation where a pedal-activated rotation of the pivot bearing 31 of the pedal arm 34 about the pivot axis 30 occurs, as a result of which the sliding base 27 of the connecting member 23 reaches the second extreme position in which the transmission is maximum.

Closing a door from its open state - FIG. 5a, 5b, 5c, 5d, 6b

The control component A28 and the control component B29 (if installed) are in the activated position (as shown in FIGS. 5a, 6b), and the rotary element 5 is close to the main position when the lock 7 is deactivated. The opening element 14 applies only residual force. The closing element 17 develops full power, but its action is blocked due to the fact that both ends are opposed by the door leaf 1.

If the door leaf 1 is stopped immediately before the initial position of the pivot element 5, and as a result, the inertia effect of the door leaf 1 (for example, while holding the foot) is eliminated, the door remains open, since the opening element 14 no longer has sufficient force to deactivate the lock 7, which abuts against the stopper 6 located on the housing 20 and, thus, on the frame 3 or wall 2.

If there is no stop of the door leaf 1, then the inertial force of the door leaf 1 together with the fist 22 causes the point of contact with the lock 7 to rest, resting its other end on the stopper 6 located on the body 20 (and, as a consequence, on the frame 3 and wall 2) that deactivates the lock 7 and the rotary element 5 (as shown in Fig. 5c). When this rotary element 5 reaches its original position.

The opening element 14 does not apply a pressing force or power, since the action of this element is blocked at both ends by the counteraction of the frame 3 or the wall 2. The closing element 17 develops full power, since the action of this element is unlocked by the end of the closure 7 being deflected by the stopper 6. Supporting arm 19 the closing element 17 counteracts the door leaf 1, and the gripping 18 of the closing element 17 acts on the pivoting element 5 and, thus, on the stopper 6 located on the lid 20, and through this then the frame 3 and the wall 2 (as shown in Fig. 5d).

The deactivation of the lock 7 made it possible for the door leaf 1 to return to the closed position under the influence of the closing element 17.

The proposed solution has a number of technical and economic advantages, including the ability to install on an existing door leaf 1 and the fact that this solution is not significantly affected by the function and operation of the door leaf 1, even if the installed opening and closing mechanism is not used I, the deactivated closing and opening mechanism I is used only as a closing device.

Industrial applicability

The present invention is applicable in all areas of technology where it is necessary to open and close the door so that there is no touching the door with a person’s hand for reasons of hygiene, or even in cases where opening by hand is difficult, for example, if a person opens the door with his whole hand. A useful function also consists in the possibility of stopping the door in the open position for passage, for example, of a hospital stretcher, as well as automatic closing with only a slight impulse in the direction of opening or closing. As well as in other areas in which it is possible to use the automatic forward and return functions.
